According to security officials, Lebanese forces have fired on Syrian aircraft that entered into the country’s airspace.

The last time Lebanese military took action to prevent Syrian warplanes from violating its airspace was near the beginning of the Syrian conflict three years ago as reported by Al Arabiya.

The only times Syrian forces have fired toward Lebanon in the past were when they were trying to stop rebels from fleeing to the neighboring country or from sheltering in Lebanese towns.

The Lebanese officials claim that the military opened anti-aircraft fire at two Syrian planes on Monday after the aircraft bombed the border town of Arsal which is close to the eastern Lebanese border.

There was no immediate comment on from the Lebanese military or the Syrian government and officials spoke on condition of anonymity as they were unauthorized to speak to the press.
